HAND ATTACHMENT FOR TREADLES.

SPECIFICATION formingpart of Letters Patent No. 369,235, dated August 30, 1887.

Application tiled June 30, 1887'.

' To all whom it may concern.:

' companying drawings, in whicha Figure lis a side elevation, partly in section, showing a handle attachment connected to a pitman. Fig. 2 is a detail perspective View on a larger scale than Fig. l, showing a method of securing a handle to a pitman. Fig.

3 is a side elevation, partly in section, of a modification. Fig. 4 is a side elevation of Fig. 3, seen from the opposite side from that seen in Fig. 3. Fig. 5 is a detail View of part of the bracket of Fig. 4. Fig. 6 is a 4side elevation o f a modification. Fig. 7 is a section in the plane xx, Fig. 6. Fig. 8 is a section in the plane y y, Fig. 7. Fig. 9 is a detail view of a clamp.

Similar letters indicate corresponding parts.

The letter A indicates a fly-wheel, mounted, as usual, on acrankshaft.

B is a pitman connected to the crank-shaft, and C is a source of power, such as a treadle connected to the pitman.

D is a handle having a shank or stem, E, entering a suitable head, F, of a bracket, I. The head F, as seen in Fig. 2, is in the form of an open socket, or is provided with a channel open at both ends, so that the stem E can be slid back and forth in said socket, or inserted into said socket from either end until the handle D is in a position suitable to the operator. A clamp or set-screw, H, serves to hold the stem E in its proper position.

Instead of having but one channel, as seen in Fig. 2, the head F may have ltwo or more handle -'receiving channels, as indicated in Figs. 3, 4, 6, 7, and 8, whereby the position of the handle D and its stem El can be considerably. varied, as desired. Said head Finay 5o also be made divided or in several pieces, as

seen in Figs. 6, 7, and 8, instead of being in one piece, as seen in Fig. 2.

In Figs. 6, 7, and 8, a screw, G, is shown, serving to hold the sections or pieces of the head F together. The screw G enables the sections of the head F to be spread or separated, so as to receive stems E of different thicknesses. In place of one screw G, several such screws may be applied, if desired.

The bracket I is secured to the pitman by a clamp, K, having a clamping-screw, L. By causing the clamp K to engage the pitman B and the bracket I, as seen in Fig. 6, and then tightening the screw L, said bracket willbe firmly secured to the pitman. In Fig. 6 the bracket I is shown as having steps M N, of different heights, on the outside of said bracket.

These steps enable the clamp to engage pitmen B of various thicknesses,` since if the pitman should be so thick that the clamp K could not grasp the step M said clamp can be moved so as to grasp the lower step, N, and thus secure the bracket in place. Again, if the pitman B should be so thin that the clamp-screw L would be too short to engage the lower step, N, then said clamp can be moved so as to cause the screw L to engage the step M, thus again securing the bracket in place. In Fig. 6 the bracket I is shown as having lugs vO engaging the pitman B, whereby thebracket I is steadied.

If desired, the bracket I may be provided with lugs P. rIhe clamp can be steadied by being caused to rest in the space Q between the lugs. y

What I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with a crank-shaft and with the pitman which serves to impart motion to said shaft, of a bracket having a han- `dle-receiving socket open at both ends and a clamp for securing the bracket to the pitman, substantially as described.

2. The combination, with a crank-shaft and with the pitman which serves to impart motion to said shaft, of a bracket having two or more handle-receiving sockets running in different directions, and a clamp for securing the bracket to the pitman, substantially as described.

3. The combination, with a crank-shaft and with the pitnian which serves to impart motion t0 said shaft, of it bracket, a divided head formed in said bracket, one or more handlereceivng channels formed in said head, one or more screws for pressing the sections ofthe head together, and :L cla-m p for securing the bracket to the pitnmn, substantially as described.

4. The combination, Wit-ha crank-shaft and with the pitman which serves t0 impart m0- tion to said shaft, of :t bracket having; a handIereCciVng socket, two or more steps 0n the outside of said bracket and situated at differ-
